This is LNWOB. Overall length is 16" (bar is 8.5" LOL!) Everything works: 

• pull the starter cord "running sound"
• On Off switch allows operation or not
• dial up sound and volume dial
• chain goes around

SUPER Clean. I own (2) REAL STIHL saws and it was a pleasure to source this for YOU!!!!!

I can't find hardly a scratch on it. I didn't have to clean it! This unit is SWEEEET!!

Be Blessed.
